Pengpeng Hou 460511c11f arc: validate DT CPU map strings before parsing them ...

arc_get_cpu_map() fetches the possible-cpus or present-cpus property
from the flat DT and immediately passes the raw pointer to
cpulist_parse(). That parser expects a NUL-terminated text buffer, but
this path does not prove that the DT property is terminated within its
declared bounds.

Reject unterminated CPU-map properties before handing them to
cpulist_parse().

Changes since v1:
- fold the NUL-termination check into the initial lookup test, as
  suggested by Vineet Gupta
